# KeyManagerFactorySpi

`public abstract class KeyManagerFactorySpi`
`extends Object` ``

java.lang.Object
↳ | javax.net.ssl.KeyManagerFactorySpi

This class defines the Service Provider Interface (SPI) for the `KeyManagerFactory` class.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular key manager factory.

See also:

- `KeyManagerFactory`
- `KeyManager`

## Summary

### Public constructors
`KeyManagerFactorySpi()`

### Protected methods
`abstract KeyManager[]` | `engineGetKeyManagers()` Returns one key manager for each type of key material.
`abstract void` | `engineInit(ManagerFactoryParameters spec)` Initializes this factory with a source of key material.
`abstract void` | `engineInit(KeyStore ks, char[] password)` Initializes this factory with a source of key material.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public constructors

### KeyManagerFactorySpi

    public KeyManagerFactorySpi ()

## Protected methods

### engineGetKeyManagers

    protected abstract KeyManager[] engineGetKeyManagers ()

Returns one key manager for each type of key material.

Returns
`KeyManager[]` | the key managers

Throws
`IllegalStateException` | if the KeyManagerFactorySpi is not initialized

### engineInit

    protected abstract void engineInit (ManagerFactoryParameters spec)

Initializes this factory with a source of key material.

In some cases, initialization parameters other than a keystore and password may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate `ManagerFactoryParameters` as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters implementation to obtain the needed information.

Parameters
`spec` | `ManagerFactoryParameters`: an implementation of a provider-specific parameter specification

Throws
`InvalidAlgorithmParameterException` | if there is problem with the parameters

See also:

- `KeyManagerFactory.init(ManagerFactoryParameters)`

### engineInit

    protected abstract void engineInit (KeyStore ks,
                    char[] password)

Initializes this factory with a source of key material.

Parameters
`ks` | `KeyStore`: the key store or null
`password` | `char`: the password for recovering keys

Throws
`KeyStoreException` | if this operation fails
`NoSuchAlgorithmException` | if the specified algorithm is not available from the specified provider.
`UnrecoverableKeyException` | if the key cannot be recovered

- `KeyManagerFactory.init(KeyStore, char[])`
